Hi, Even as you attached a reproducer, could you still attach the stack-trace (or other useful infromation, if any)? Thanks. Without it, it requires somebody looking at the bug to reproduce it -- which takes several minutes at best. In the worst case, the reproducer might not work for some reasons... Presumably, you tested the reproducer, so it should be almost no effort to attach the information which you already have(??). If it requires unreasonable effort of you to get more information, you are welcome to say so and don't provide it. But then at least say: "I cannot get a stack trace because XYZ", so you won't be asked for a stack trace. Thanks!! Hi, this is the backtrace I get on master:
<info> [1606133820.6775] manager: (enp8s0): assume: taking over an initramfs-configured connection

Created attachment 1732431 [details] reproducer by bgalvani Description of problem: When Networkmanager is built with assertions, there is a crash when NetworkManager is starting after setup done by network-legacy dracut module. Version-Release number of selected component (if applicable): nm-1-26 branch (maybe even sooner) How reproducible: when NetworkManager is built with assertions Steps to Reproduce: run corresponfing NetworkManager-ci test: dracut_legacy_iSCSI_ibft_table or run attached reproducer Actual results: NetworkManager crashes (Segmentation Fault) Expected results: There should be no crash.
